I disagree with this - I do around 100-140k as Blood (sometimes 225k on some fights like Tortos, Durumu, even Lei Shen) but perhaps I am a little old school, cause well, I like to time my Death Strikes so with that, I end up throttling somewhat - and I still end up with better survival.
I believe if the DPS really...REALLY have to rely on Tank DPS to kill a boss (which should never be the case), then the DPS need to re-evaluate their playstyle, since they cannot meet the DPS requirements they themselves need to achieve, and the DPS need to be replaced.
If blizzard wants Tanks to do DPS, then they need to just remove Tank Stats/Gear, and just let tanks wear flat out DPS gear and we all just gear the exact same, and use the same gearset for both an actual DPS set as well as to Tank with.
Also the spamming Taunt on CD is an exaggeration, but DPS for a Tank should be 2nd thought at least, but not top priority. To quote Reniat:
"While Tank DPS is important, surviving is always #1 and being an unstable tank is a hefty price to pay for extra dps. If you aren't stable there had better be a good reason for that extra dps, or you are just making it harder on your healers for no reason, which is obviously not good. If you are trying to rank, make sure your healers are on board first."
Perhaps this is why I always,
ALWAYS outlast my OT on progression and farm kills - he focuses on a lil more DPS (which we do NOT need, trust me) thus he dies, while I end the fight full health!
So yeah...I'll stick to being the last man standing. If the raid needs more DPS I'll do it (but the DPS better evaluate themselves and up their throughput) thus I'll add some extra through means such as Runeforge Swapping or using a trinket. But we have some baller DPS in my raid group. So I'll stick to my survival build so we can continue to 2-heal fights.
